[摘要]：Previous research on histamine H-3 antagonists has led to the development of a pharmacophore model consisting of a central phenyl core flanked by two alkylamine groups. Recent investigation of the replacement of the central phenyl core with heteroaromatic fragments resulted in the preparation of novel 3,5-, 3,6- and 3,7-substituted indole and 3,5-substituted benzothiophene analogs that demonstrate good to excellent hH(3) affinities. Select analogs were profiled in a rat pharmacokinetic model. (C) 2010 Elsevier Ltd. All rights reserved.
